MSK071C-0450-NN-M1-AG2-NNAN
MSK IndraDyn S Synchronous Motors
The MSK071C-0450-NN-M1-AG2-NNAN from Bosch Rexroth Indramat, part of the MSK IndraDyn S Synchronous Motors series, delivers a 14.0 Nm continuous torque at standstill and achieves a 44.0 Nm peak torque for demanding load changes. It operates with a continuous current of 10.4 A and tolerates up to 40.1 A maximum current for rapid acceleration profiles. This IndraDyn S Synchronous Servomotor features a plain shaft of 32 mm diameter for direct coupling to high-precision drives. Its sealed housing meets IP65 protection, enabling reliable performance in harsh industrial environments.
The motor’s Natural convection cooling eliminates the need for external fans while ensuring thermal stability, provided smooth airflow around the frame. A robust A-Side power connector supports secure power delivery, and the optical multiturn encoder with 128 signal periods resolution and Hiperface interface ensures precise position feedback. The encoder’s Multiturn Absolute turn type maintains absolute position data across power cycles without homing. A built-in electrically-released holding brake provides 30 Nm of holding torque to secure loads during standstill. Its Winding Inductivity of 6,700 mH and Winding Code 0450 deliver smooth current control and stable torque output under varying dynamic conditions.
Engineers benefit from the motor’s compliance with standard MSK71C mounting dimensions, enabling drop-in replacement and seamless integration with Rexroth IndraDrive controllers. The combination of continuous current stability, robust IP65 sealing, and precision feedback via Hiperface enhances system reliability and reduces maintenance intervals. This motor excels in packaging, CNC machining, and automated assembly applications requiring high torque density and precise motion control.

Frequently Asked Questions
What do the 14.0 Nm continuous and 44.0 Nm maximum torque ratings on MSK071C-0450-NN-M1-AG2-NNAN imply for duty-cycle planning?
The continuous torque defines steady thermal capability with natural-convection cooling, while the peak rating supports short acceleration bursts. Its proper thermal modeling and cycle-time averaging ensure overload segments stay within time/temperature limits for reliability.
How does the M1 Hiperface optical multiturn encoder in the MSK071C-0450-NN-M1-AG2-NNAN aid servo-loop stability and startup behavior?
It provides 128 signal periods with absolute multi-turn data retention. It removes homing after power cycles, accelerates commissioning and supports tighter position control with finer interpolation in closed-loop motion.
Why specify a 32 mm plain shaft on MSK071C-0450-NN-M1-AG2-NNAN, and how should it be coupled?
The plain shaft enables backlash-controlled, force-fit clamp hubs or precision bellows couplings for direct drives. Its radial/axial load limits and bearing-life assumptions are important to consider when selecting hub lengths and overhung loads.
What does the IP65 enclosure mean for installing this MSK071C in washdown or dusty cells?
The IP65 indicates dust-tightness and resistance to low-pressure water jets when connectors are fully tightened for including the 240° rotatable sockets. It is important to avoid fluid pooling at the shaft seal, particularly in vertical, shaft-up orientations.
How is the 30 Nm electrically-released holding brake on MSK071C-0450-NN-M1-AG2-NNAN applied in vertical axes?
The 24 VDC release brake secures loads during standstill, its size mechanisms for static torque exceeds worst-case gravity and disturbance torques. It is for holding device, while dynamic stopping belongs to drive/PLC safety functions.
